Hi, I put a lot of cast inside my PR and I'm don't very like it...

Do you prefer using cast, "# type: ignore", a Typed Dict (but will force typing_extension for old python version), a pydantic model or create a Metric Object ?

Hi @bblommers, I hope you're doing well :)

I'm a little bit lost, my test suite is failing on test server. I can replicate it on local, it seems that the sagemaker metrics backend is not created in server mode. Do you have any idea ?

The routing needed some additional logic to deal with the multiple Sagemaker services - that's fixed now.

LGTM - thanks @YHallouard!
